World at the Earth’s Center

Pellucidar, the
greatest of Burrough’s Lost World, is a primeval realm within the world’s
hollow center.Aminiture sun hangs
suspended within this center, shedding endless light. Pellucidar’s landarea is
roughly in the position of the surface world’s oceans, and vice versa, giving
it a far greater land surface. Because of its timeless nature, and vast
surface, myriad creatures from all the ages of the Earth’s prehistory swarm
throughout this land. And not one, but many sentient races have evolved within
Pellucidar, possibly because of the absence of the waves of mass extinction
that have elapsed on the surface of the earth.

Beasts of Pellucidar

Tandor

The tandor is the mighty woolly mammoth of the ice age,
the great shaggy progenitor of the elephant armed with gigantic swirling ivory
tusks. The below scene, done in ink by frazetta, depicts a scene of raw primal
fury fromboth“Tarzan at the Earth’s
Core”, and “Back to the Stone Age” where a ravening tarag pack brings down a
bull mammoth. The great bull tandor is a magnificent picture of primal,
indomitable power as he battles them his final breath.

The mammoth is significant in
“Back to the Stone Age” as Von Horst befriends a wise old mammoth known to the locals
as “old white” from the white patch on his side. Von Horst rescues the mammoth
from a slow agonizing death. In gratitude, Old White comes to his human
friend’s aide when Von Horst is captured by the Mammoth Men, and again when he
fights against the Ganak Bison Men, a race of humanoid bovines.The Mammoth Men, by the way, were a human
tribe who learned to train and ride the mighty tandor as war mounts. This made
the Mammoth Men a terror to the other tribes.

Tarag

The Tarag is the great saber-tooth tiger of the stone age. They
are present throughout the Pellucidar series. The largest saber-tooth species
known from the fossil record was Smilodon Fatalis of South America,
larger then the modern Siberian tiger, and considerably more massive in build.
It was thought to have been able to bring down mastodons and giant ground
sloths that shared its world. Burroughs greatly inflates the animal’s size,
making them close to the size of a buffalo, and the length of their saber-fangs
(actually just over nine inches) to eighteen! The tarag of Pellucidar is
gorgeously striped with gold and the glossy black of anthracite coal.

David Innes’ first encounter of a tarag is in the death arena of
the Mahar City of Phutra, where it was pitted against thag, the giant aurochs
of primeval Europe. The two monsters ignore their intended human victims and
battle each other to the death in terrific fury. In “Pellucidar”, the second
book in the series, David and Dian are the two intended victims, pitted in the
arena against a mammoth tarag. Tu-ul-sa, the Mahar whose life Innes spared,
dispatches three great thipdars, “the flying reptiles that guard the queen” to
carry the tarag out of the arena, saving the lives of Innes and his mate.
Tarags are sometimes encountered alone, but occasionally band into vast apcks
of over a hundred or more members. These packs are able to fell the largest of
the inner-earth herbivora. Interestingly enough, scientists now believe that
some species of saber-tooth, notably S. Fatalis, may actually have
hunted gregariously, in order to bring down difficult prey.

Dyrodor

This is a huge plated monster of
Pellucidar, described in “Tarzan at the Earth’s Core”. It most closely
resembles the stegosaurus, the species with which it may be identical, though
some ERB-philes have suggested otherwise, because of the creature’s apparent
carnivorous habits, and extraordinary gliding ability. The huge, cartilaginous
plates sported by the reptile enable it to become airborne if it leaps off a
high precipice.

Dyryth

Megatherium, the giant ground sloth of the Plesticene, a
huge, shaggy beast the size of an elephant. Burroughs describes the dyryth as
having a short trunk not unlike that of a tapir. The ground sloth of the
surface is not known to have had one, though the marsupial “ground sloth” of
South America did possess such a trunk, and somewhat resembled the dyryth.

Ryth

The giant cave-bear of the ice-age.
This shaggy monster ranged over the Eurasian taiga, south of the great ice
-sheets, on the outer crust. Its scientific name was Ursus Spaleaus. Larger
than any modern ursine, it was actually more herbivorous than its modern
cousins, and was likely not very fierce at all. Not so the giant short faced
bear of North America—this beast was not only larger even than its European
counterpart, it was long-limbed, fast, and strict flesh eater—and able to fell
a moose with a single swipe of its gigantic paw. Burroughs only describes the
better known cave bear, however, and as with the tarag, he greatly inflated the
animal’s size for dramatic purposes. The lowland ryths were about the size of
an ox; the ones living in Pellucidar’s mountain ranges, far above timberline
were white-furred and gigantic—fully the size of a bull elephant!

Sithic

The Sithic is a labrinthadon, a
giant, carnivorous amphibian of monstrous size, which David Innes encounters on
his first venture to Pellucidar in “At the Earth’s Core”. It inhabited the
outer crust during the Permian and Triassic eras. Actually, huge labrinthadont
amphibians continued to linger on through the age of dinosaurs in the southern
polar swamps. But these later animals, such as Koolasuchus, had jaws that were
less crocodile-like than their ancestors. The sithic, sporting a toad-like
body, and mighty crocodilian-style jaws, most resembles the original
labrinthadon. Some illustrators, like in the Frazetta illustration below, and
in the Mike Grell-illustrated Tarzan: the Savage Heart, published by
Dark Horse, incorrectly show the sithic as being scaled and resembling a huge
alligator. The true labyrinthodon, both described by Burroughs, and by
paleontologists, had a wet, moist, pulpy hide, like any other amphibian.

Jalok

Jalok are hyeanodons of the
Eocene, dog-like carnivores found throughout the inner earth. Burroughs
describes them as ancestral to modern canines. There are two Manning comics-one
Pal-ul-don strip, and an issue of the Dell comic in which Tarzan explores a
hidden plateau where extinct mammals still roam—where they are simply huge
(prehistoric) hyenas. Actually, these beasts were related to neither hyenas nor
wolves, (though they somewhat resembled both in appearance and habits) but were
members of the creodonta, and group of flesh eaters, that were related to no
modern carnivore.

Thipdar

The Thipdar is the gigantic
pteranodon of the Cretaceous age, and the most feared predator of Pellucidar’s
skies. One thing notable about thipars is that they are used as pets and guard
animals by the Mahars, Pellucidar’s formerly dominant race. This may be because
both Mahars and Thipdars are related, but pteranodons are still of animal
intelligence within Pellucidar, and belong to the pteradactyl order of the
pterasauia, rather than the rhamphorinchids, to which the Mahar belong.The Mahr ruler Tu-ul-sa uses them to rescue
David Innes and Dian the Beautiful for the a giant tarag in the amphitheater of
death. Perhaps the most memorable thipdar scene occurs in “Tarzan at the
Earth’s Core”, in which the Ape Man finds himself borne off in the talons of a
female thipdar, and nearly tossed into a gigantic nest among her squealing
brood. Varients have this scene have appeared on the Filmation cartoon
adaptation of the novel, Lin Carter’s Zanthodon series (itself a Pellucidar
take-off), the Raquel Welch 60s’ cult film One Million Years B. C., the Ka-Zar
the savage comic book series, and elsewhere. Again Burroughs takes some
liberties with the animal’s size. He describes the wingspan as about
twenty-five feet, but pterosaur’s were so light weight, they would not be able
to bear off any human-sized creature. An even larger pterosaur, Quetzalcoatlus,
whose wingspan measured fifty some feet, would, in fact been able to carry off
human-sized prey, but it was unknown when Burroughs wrote his stories. He also
describes pteranodons as having teeth, when in fact, the name “pteranodon”
translates from the Latin as “wing-toothless”. One lesser-known detail is that
female pteranodons lacked headcrests, but this, too, was unknown in Burroughs’
time. Comics art veteran Russ Manning, writer of some of the finest newspaper
strips featuring the Ape-Man, has one character exclaim, on one of Tarzan’s
syndicated forays into Pellucidar, that the pteranodons that attack the 0-220
are “huge—much bigger than any that ever lived on the Earths’ surface”. In
Burroughs’ fictional universe, however, it appears that some members of this
same species did reach approximate size. We know from “The Eternal Savage”,
when a gigantic pterandon bears off Nat-ul to her nest, yet another variant on
the dramatic scene pictured below.

Zarith

The zarith is the tyrannosaurus
rex of Pellucidar, most dreaded and terrible of all terrestrial carnivores. It
is only encountered once within the series, in “Back to the Stone Age”, when
Von Vorst and La-Ja encounter a juvenile specimen the Forest of Death, about to
devour a Gorbus, a member of a weird, cruel, albino race. Von Horst is able to
kill the beast. La-Ja informs him that adult zarith feed on the giant Bos, the
aurochs, and on the mighty mammoth. Possibly zarith are rare, and seldom
encountered, since too great a number would lay waste to the prey species.
Unlike the thipdar, and most wildlife of the Earth’s Core, the Pellucidaran
t-rex is often misnamed in pastiches, such as John Eric Holmes’ Mahars of
Pellucidar (where it is called a “dryath”), and in the Filamtion TV series
(where it is called a “zabor”), possibly since it is barely mentioned in the
series. The Dark Horse publication “Tales of Pelluciadar” drawn by Thomas
Yeates, and otherwise a decent effort, refers to the T-rex of Pellucidar as a
“Garth”, which is a Pal-ul-don term from the comics, and not even authentic
Burroughs. The Pal-ul-donian term “gryf” is used for the triceratops in the
same story. Only the Dyrodor (stegosaurus) is named correctly. The first
inconsistency could be explained away in that Tarzan had not encountered a T-rex
in Pellucidar until now, and used the more familiar Pal-ul-don term instead. He
should have known to use the Pellucidaran “Gyor” for triceratops however, as he
did indeed encounter one on his first venture to the inner world.

Gyor

The triceratops of the inner earth. This beast, as Tarzan
notes, is strikingly similar to the Gryf of Pal-ul-don. Though possessed of a
terrible temper however, the gyor is an herivore, unlike its evolved Pal-ul-don
counterpart on the surface. It is also similarly marked, though much lass
brilliant in coloration. It is possibly a form of triceratops virtually
unaltered since its original form. The gyros roam the mighty plain known as the
Gyor Cors in vast horns. The Horib lizard-men relish the flesh of the
three-horned beasts, and often hunt them on their Gorobor mounts, lassoing and
subduing the triceratops with strong ropes.

Thag

The huge bull aurochs of
Pellucidar, known scientifically as the Bos Primenigus. This creature
was the giant ancestor of modern cattle. Herds of aurochs ranged throughout the
great broadleaf forests of Europe from the last ice age, up until early
historical times. The last few died out with the coming of the industrial
revolution. One of the most memorable scene involving a thag in the Pellucidar
series takes place in At the Earth’s

Core, in which a tarag and a thag battle to the death in the
Mahar arena. Another such scene between predator and prey occurs early in Tarzan
at the Earth’s Core.

Sadok

Referred to as the giant
“two-horned” rhinoceros, the sadok is mentioned occasionally in At the
Earth’s Core. Just what speces it represents is not clear. It may refer to
the Plesticene wooly rhino, Coleodonta, as some have suggested, making it the
same species as “Ta” the wooly rhino from The Eternal Savage. But not
only is this species two horned, but so are the two modern species of African
rhino. The Burroughs Encyclopedia identies the sadok with the brontotherium, a
huge titanothere of the Oligocne. Male members of this species had a single
horn that branched into a Y shape. It is probably the most likely candidate for
the sadok, and the Clark A, Brady’s Burroughs Cyclopedia cites it as such.
However, there was another mammal of the late Eocene that is a possible
candidate. This is the mighty arsinotherium of lower Egypt. This beast also
resembled a large rhinoceros, but sported two massive horns, not one in front
of the other as in its modern counterparts, but side by side on its broad
snout.

Lidi

The giant diplodocus of
Pellucidar, a giant sauropod dinosaur related to the better-known brontosaurus.
Burroughs describes it as a plains-dwelling animal. The human tribes of thuria
have learned to domesticate the plains lidi as formidable war-mounts.

Gorobor

Giant lizard-like reptiles which
serve as steeds to the reptilian Horibs. They are as lightening-fast as their
smaller counterparts, and fastest thing within the inner earth. They are
similar to the herbivorous cotlyosaurs of the lower Permian, with which they
may well be synonymous.

Azdyryth

This term refer to a giant
marine reptile of Pellucidar’s oceans. It’s name translates to “sea sloth” or
“sea megatherium”. Though the animals in the Manning illustration below are
without question some form of plesiosaur, the azdyryth is most accurately
identified with the ichthyosaurus, a great fish-like marine lizard, with
mighty, elongated jaws bristling with teeth.

Tandoraz

This is the name given to the
plesiosaur, the sea-mammoth of Pellucidar’s oceanic realms. It is describes as
having a long neck, and a seal-like body.

Actually ,the name of the
monsters above would translate roughly as “sea bear”, a name not precisely used
by Burroughs himself. There existed on the outer surface several species of
plesiosaur after all, the largest being the elasmosaurus, the species with
which the tandoraz may be identified.

Ta-ho-az

The “sea-lion” of Pellucidar, a
monster that, from the descriptions appears to be yet another species of
plesiosaur, albeit one smaller, though no less ferocious than the tandoraz.

Aztarag

Another ferocious marine
denizen, this reptile’s surface counterpart has not been officially recognized.

Tylosaurus

This was one of the most feared
predatory reptiles of the upper Cretaceous period. Burroughs does not relate
the native term for this reptile, though it is possibly synonymous with the
aztarag.

Hydrophidian

This is one last reptilian
monster know to be indigenous to Pellucidar’s seas. This is a serpentine
creature David Innes rescues Ja the Mezop from in the first book, and in the
St. John illustration below, merely referred to as a “hydrophidian”. No
scientific or Pellucidaran term is used to identify it.It is snake-like in from, with small horn-like
protuberances over each eye, a jetting, forked tongue, and goggling eyes. It
may or may not have had a surface counterpart in prehistoric times.

Codon

The giant dire wolf of the
Plesticene. These pony –sized wolves are huge enough to overtake most prey
single –handed, and only hunt the giant tandor in packs.

Orthopi

The diminutive ancestor of the
modern horse, known to science as the eohippus or hyracotherium. It lived
during the Eocene period, shortly after the demise of the dinosaurs.

Dyal

The phorohacas, huge predatory
bird of Miocene S. America that was over ten feet tall, with a mighty
eagle-hooked bill, and powerful legs that made it near impossible to outrun.
Tarzan and his companion Tar-Gash (a sagoth) battle and slay one in Tarzan
at the Earth’s Core. The dyal is used as steed by some Pellucidaran tribes,
even though it is ferocious and difficult to train. In the comic illustration below,
Tarzan battles a tribe of Pellucidaranpurpleskinned cannibals who use dyals as war-mounts.

Dimorphodon

Mere mention is made of this
flying reptile, which Burroughs says is a “smaller cousin of the thipdar”.
Dimorphodon lived during the Triassic age, the first era of dinosaurs, on the
surface, and was one of the more primitive pterosaurs

Tracodon

This is a huge, elephant sized
herbivorous “duck-billed” dinosaur of the late Cretaceous. Though innumerable
species of reptilian life make the Phelian Swamp their home, this animal is the
only one given direct mention, as it is seen being devoured by one of thetitanic serpents which infest the region. It
is more correctly known to science as the anatosaurus. Like the dimophodon, it
is not revealed what the native term for this beast is.

Snakes

Snakes of overwhelming
proportions infest the Phelian swamp, where they apparently exist at the
pinnacle of the food chain. Some grow large enough to swallow adult dinosaurs
of good-sized species. No serpent of the outer crust is known to have attained
such colossal proportions. Though giant serpents did exist during the
Cretaceous, the largest was only a little bigger than the largest living snake
today, the anaconda.

Trodon

This is an entirely fictitious monster,
as Burroughs himself admits when he tells us that its restoration was never in
any book, its skeleton never in any museum. Perhaps it is entirely Pellucidaran
in origin, or perhaps it is one species whose surface counterpart will remain
undiscovered. The trodon is somewhat pterosaurian, having a head that is
“pterodactyl-like”, and mighty leathern wings. Its’ body, however, somewhat
resembles a gigantic winged kangaroo, with powerful rear legs, and a massive
tail. Its forearms are separate from the wings, and with them the troodon can
easily grasp its prey. It also has a pouch with which it transports its victims
(and perhaps its young, after they hatch?). Burroughs refers to the Trodon as a
“giant marsupial reptile”, though technically this is impossible, since the
marsupial reproductive system is strictly mammalian. The trodon paralyzes its
victims’ nervous system with its barbed tongue. The victims are then left in
the adult trodon’s rookery until the eggs hatch, and the young troodons devour
their screaming victims alive.

Ta-ho

This is the mighty cave-lion of
Pellucidar. Scientist believe that the cave lion of the ice age to be the
largest cat that ever lived, bigger even than Smilodon Fatalis. From
cave –renderings of the animals discovered in Europe, it is almost certain that
adult male cave-lions lacked manes. In The Eternal Savage, Burroughs
incorrectly describes a cave lioness as being “maned like her lord”. One inner
earth tribe has learned to domesticate the ta-ho as companions and hunting
animal, as two other tribes have done with the jalok and the tarag,
respectfully. The Mike Grell illustration from the dark Horse comic series “The
Savage Heart”, depicts a cave-lion accurately, without a mane.

Hyena Spelea

This is the giant cave hyena of
ice age Europe, which grew larger than a modern African lion. The native name
for this animal is unknown.

Dinotherium

This is a huge elephantine
creature with mighty downward curving tusks, which lived on the earths’ surface
during the Miocene. It is one of the few innumerable Pellucidaran herbivorous
mammals mentioned directly in both Tarzan at the Earth’s Core, and
Back to the Stone Age. Its Pellucidaran name is unknown.

Antelope

There innumerable species within
Pellucidar. Burroughs describes the most beautiful in At the Earth’s Core,
as having backward spiraling horns, and a gorgeous striped coat, patterned in
the manner of the zebra.

Maj

The mighty mastodon of
Pellucidar, a beast somewhat smaller than the tandor, with a flat head rather
than a high-domed skull.

Archeopteryx

A primitive “dinosaur-bird” of
the Lower Jurassic, having teeth, and hooked-claws on its wings. The
claw-winged avians, described once in Tarzan at the Earth’s Core were doubtless
of this species, or one of the related reptile-birds discovered by
paleontologists in recent times.

Giant Ants

Gargantuan “prehistoric” ants
are also native to the inner earth. They thrive in vast, underground colonies,
and grow huge enough to carry off humans to feed their larvae. They are purely
a Burroguhsian invention.

Ant Bear

A colossal edentate mammal which
feed on the giant ants, possibly a relative of dyryth. No such animal ever
existed on the surface.

Others….

Doubtless, many other animals
swarm though this lost world at the center of the earth, as Pellucidar is a
vast melting pot from all the ages of prehistory. John Eric Holmes, in his two
Pellucidar pastiches Mahars of Pellucidar, and Red Ax of Pellucidar, decribes
other, though he does not invent Pellucidar names for any of them. There are a
herd of elephant-like beasts in the first book, which sport great protruding
lower jaws, and are swamp dweller. These are doubtless shovel-tuskers. He also
describes a triceratops in the same book as having a much more colorful face
than the “gyor” in Burroughs own version. He also incorrectly calls a
tyrannosaurus (zarith) a “dryath”, and uses the term “gryf”(the name of the
Pal-ul-donian triceratops), as a general term meaning “giant reptile”. He has
the natives describe the brontosaurs in the next book as lidi, which is fairly
accurate, since the species brontosaurus and diplodocus are virtually
identical, and might well go by the same name. Other beasts in Red Ax
include knobby-horned rhino-like beasts that are certainly uintotheres, and
sail-bake reptiles that neatly fit the description of dimetrodon, a finback
Permian reptile. Holms makes the dimetrodons semi-aquatic predators utilizes
their fins as sailing apparatus. The fin is actually believed to have acted as
temperature regulator, but their have been other ideas as well. Holmes’
visualization of their purpose is at least as inventive (and way more
plausible) than Burroughs own for the dyrodor’s plates! Mention is also made of
the “Brontotherium and the Balucotherium” of the plains. The Jusko illustration
above depicts a “prehistoric octopus”, as one of the terrible denizens of Pellucidar’s
oceans.

Races of Pellucidar

Mahar

The Mahars are the formally dominant race within the
hollow earth. They are super-intelligent pterosaurs descended from
rhamphorynchus of the Jurassic. On the surface, the rhamphorynchus grew to no
larger than a crow, and were unintelligent. But due to some freak of
Pellucidar’s evolutionary chain, here they developed vast intellect and
stupefying mental powers. Mahars are totally deaf, and communicate
telepathically among one another, and to their servants the sagoths. They are
also deaf, but have developed a form of “musical” entertainment based on
motion. They often use a related species, the giant thipdars, as bloodhounds to
chase down escaped slaves, and guard animals. They use humans (gilaks) for
their scientific experiments, and also to serve as Mahar food, though eating
any kind of mammal is considered taboo, and not done by “respectable” members
of the species. Humans intended to serve this purpose are taken to a Mahar
“temple”, where they are imprisoned on islands surrounded by water, not unlike
an aquatic zoo exhibit. When a mahr singles out a human as victim, she fastens
her gaze on him/her, and lures the mesmerized victim into the water to be
devoured. Mahars, unlike their Jurassic ancestors are able not only to fly but
to swim as well as a seal. Mahars are also a race entirely made up of females.
Somewhere along their journey to dominance, Mahr scientists learned to
fertilize their eggs chemically, eliminating the need for males. The details of
the method of procreation are not given in the series, but Alan Gross, in his
novel Farewell Pellucidar,
includes a male Mahar who is no less intelligent, but is no larger than his
Jurassic counterparts! The idea of this extreme sexual dimorphism among the
Mahar is an interesting twist. Though perhaps some male members of the Mahar
race do exist in some far off regions of the inner world, none is ever
encountered in any of the novels penned by Burroughs himself. I wrote a
Pellucidar pastiche some years ago, which still being serialized in Frank Westwood’s
zine Fantastic World of Edgar RiceBurroughs that also features a
male mahar, only I made the male of the species even larger than the female.
Sometimes pastiches counterdict one another. I did not know at the time that
the Gross novel existed, or I would have tried to make it consistent. Actually,
Mr. Gross’s version is the more logical, as females among retiles tend to be
larger. Mahars have been depicted many times, with varying degrees of accuracy.
Among the worst are the man-in- costume examples in the film version of At
the Earth’s Core. Close to this are the Mahars in the “Blood Money and
Human Bondage” series of stories in marvels comics’ version of Tarzan. These
only faintly resemble their counterparts from the fossil record, and are too
humanoid. This version also features both male and female members of mahar
species, but this is clearly a mistake on the authors’ part. The last surviving
Mahars have evidently established a colony on Pellucidar’s moon, the Dead
World. The mahar scientists, who are depicted as male, have invented a bizarre
weapon called the “sound canon” with which they hope to retake Pellucidar. This
version quickly came under fire from Burroughs enthusiasts because of the
numerous errors. The authors seemed to have forgotten that the Mahar race is
deaf dumb and all female. Then there are the “mahars” of the recent tarzan
television series. NOTE: I did not see these, and really can’t comment
accurately, but from other sources I’ve gleaned that the Mahars do not resemble
those in the Pellucidar series at all, and are able to morph at will into
attractive human females. In the Russ Manning Pellucidar stories, the Mahars
are identical in appearance to the reptiles of Burroughs novel, and resemble
outsize rhamphorynchus.

In one strip
sequence from Manning’s dailies, he has the Mahar that David Innes mistakenly
took with him to the surface escapes and is at large in Tarzan’s Africa. Innes
believes that he takes the Mahar back with him, but it is explained that he
only takes an illusion that the Mahar placed in his mind. This, of course, is
at odds with Burroughs own version, in which the Mahar Innes liberates (whose
name is Tu-ul-sa) later spares his life in the arena. Seeking refuge in some
ancient ruins the deepest darkest region of the Congo. She recruits human
“friends” to serve her. A fanatical cult develops around the mahr by the
mesmerized humans. Any humans who disobey, or are able to resist her hypnotic
mental powers, are taken to a feeding pool for the Mahar to devour. It takes
the Ape-man himself to finally subdue the creature and free the cultists. This
opens up a whole other sequence, in which Tarzan and Korak return the Mahar to
her rightful home, and thus embark and another adventure within the hollow
earth. Frank Frazetta’s illustrations of Mahars, while among the best, are far
less accurate than those of Manning. The head of the Mahar in one of the
pictures below does not resemble its Jurassic counterpart. His pictures of the
Mahars mesmerizing their victims are too human-like. The Dark Horse comics
series “Tarzan vs. Predator at the Earth’s Core” also featured a Mahar. The
book is well-drawn, and well-scripted (more so than most of their other
Burroughs stories), but the artist seemed to have followed Frazetta’s influence
more than Manning’s. The Mahar does look a bit more pterosaur-like than Frazetta’s
though, as it should.

Sagoths

Sagoths are a race
of savage gorilla-men. They serve as slavers to the mahars.

Horibs

Horibs, called lizard-men or snake- men, are a grotesque
race of humanoid reptilians descended from lizards or lizard-like reptiles.
They are cold-blooded, and never cease to grow while living.. One specimen is
cited as being well over seven feet tall. Horibs capture humans and other
warm-bloods as food for their newly hatched young. Horibs dwell in vast swamps,
and lay their eggs in mud. They are humanoid in form with heads resembling a
snakes or lizards, and sport a pair of short horns. Eerily, they speak the same
tongue as gilaks, the humans of Pellucidar with a sibilant hiss. Their mounts
are the lizard-like gorobors, the swiftest beast in the inner earth. The relish
the flesh of the Gyor or triceratops, as a delicacy.

Ganaks

The Ganaks, or Bison-men, are a race of humanoid bovines.
Like their ancestors, they are herbivorous, though the sometimes capture human
for their cruel sacrificial rites. %hey brew a liquor called “dancing water”
for use in these rituals.

]

Gorbuses

The Gorbuses are a human-like
race with white hair, milky-white skin, and large pink eyes with red albino
pupils. They also sport tusk-like fangs with curve up from their lower jaws.
They are a cannibalistic race who inhabit the Forest of Death. It is because of
the Gorbus that the forest bears this name, as they capture any humans who
venture within. The gorbus also share some mysterious tie with the surface
world. They suffer from visions of a previous life in which they have all
killed something, and have fleeting visions that could only pertain to life
outside Pellucidar, but the origins of this mysterious race are never revealed.

Coripies

The Coripies, or “Buried
People”, are perhaps the most gruesome race to have evolved within Pellucidar.
They are an underground race native to the island of Amicop, apparently
descended from surface dwellers. They are humanoid in form, but lack aby
discernible facial features. They are totally blind, and skin covers their
eyes, which roll grotesquely beneath the covering membrane. They have heavy
fangs and webbed talons, with which they tear apart their prey. This usually
consists of cave fish , toads and lizards, but they relish the flesh of other
warm-bloods as a break from this.

Beast-Men

The beast men are a savage,
though vegetarian, race that inhabit the island named Indiana by Innes. Their
faces resemble a cross between a sheep and a gorilla. They live a peaceful
existence on the island under chiefdom of Gr-gr-gr. They harm only intruders
they feel threatened by, and basically only want to be left alone. In the dark
Horse comic series, The Savage Heart, writer Alan gross has Tarzan encounter
the tribe of Gr-gr-gr. Artist Mike Grell does a good job of rendering them,
though the sheep-like aspect of them seems absent, and would indeed be very
difficult to depict. Gross reveals that the Beast-Men, like other sentient
primate species in Burroughs universe, share certain characteristics with the
mangani, or Great Apes. For example, they share the ritual known as the
Dum-Dum, and males battttle personal combat to establish chiefdom.

Ape-Men

These are mostly akin to monkeys
than apes, being humanoid in form, but sporting long pendulous tails. They
quite hairless, with glossy black skins. They somewhat resemble the tailed
races of the lost land of Pal-ul-don, on the surface. They live high in
tree-top villages, and sometimes take humans as captive.

Saber-Tooth Men

These are similar to the Ape-Men, and possibly related to
them. being also hairless and black-skinned, and with long prehensile tails.
These, however, often capture and devour any gilaks they capture. Unlike the
Ape-Men, Saber-tooths sport a pair of saber-fangs extending from their upper
jaw.

Others….

It is quite likely that, had Burroughs continued the
series, more races would be found thriving in the far-off vastness of the inner
world. Pelludicar’s land-surface, after all was nearly double the lad area of
the surface. There are some new races that have shown up in the pastiches. For
exapaple, in Alan Gross’s Farewell Pellucidar, there is an aquatic race
of beaver-like humanoids, who inhabit dam-like “villages” in Pellucidar’s rivers.
These beings are covered with a sleek coat of waterproof fur, and have large,
flat tails. They feed on other aquatic animals such as the fresh-water
plesiosaur, and often use live-baits, which sometimes includes humans. In Andy
Nunez’s pastiche The Moon Maid at the Earth’s Core, reveals a race of humans
who have a fairly advanced technology, and who inhabit Pellucidar’s moon.The moon maid of the title is named
“Ee-lah-nah”, almost a reverse spelling of“Nah-ee-lah”, the heroine of Burroughs own novel, The MoonMaid!
Incidentally, it is quite likely that, in Burroughs universe, that Pellucidar’s
moon would have been inhabited as well, but by what manner of being one can
only speculate. In Willian gIlmore's Pellucidar pasticxhe, published in the 1971 issue of "the Burroughs Bulleten", explorers to Pelluciar encounter another weird rac inhabiting the Dead World (I forget their name). They are a race of short, squat, apish beings, rather like dwarf orangatangs, and covered in orangish hair. Due to the gravitational pull of the central sun, the moon's inhabitants, are "frozen", during the days, and active only when the land is in shadow. The moon is also inbhbited by a race of humans as well, and these are preyed upon by the cannabilistic ape-like race. One thing missing in this story is a native princess for one of the main cxhracters to fall in love with, even though one of the Jeff Jones iustrations shows a curvaceous girl as one of the the captives. The lunar humans are dealt with only sparingly in this novel, although the Dead Wold, and its physics are greatly elaborated upon. It is a shame Burroughs himself never took up the question. In the
Marvel comics series, in which the Dead World serves as a last refuge for the
Mahar race, there appears to exist there a squat, humanoid reptilian race who
act as servitors to the mahrs, but this is never explored in detail. In the
Russ manning strips, the moon is also shown as a place of refuge for the Mahr
race. The moon is hollow with a crystalline center in the Manning version, and
the retiles use the crystals to augment their collective mental powers to cause
havoc on the earth’s surface.
